Phil's Rambling Rants
I have a problem with people eating endangered species. I guess I would have to relax that somewhat if there was nothing else to eat and it was a matter of eat or die. However, I get the impression this eating is occurring in the US (Chicago butcher), so "eat or die" is not an issue here.
Deliberately killing a lion disturbs me because lions are rare, but eating something that hasn't been killed--that died of natural causes--seems kind of disgusting. It's the killing, though, that strikes me as potentially an issue of right and wrong, the eating something dead of natural causes strikes me as an issue of disgust--a matter of taste, and arguably practicality, that doesn't really have much to do with right and wrong.
And deliberately killing a lion so people can show off (by eating something very unusual and presumably expensive)--well, let's just say that I think sometimes the purpose of an action can have redeeming features that help reconcile me to an ethically dubious situation. But I don't see any redeeming features in this purpose.
